How will Depo-Provera CI change my periods?
- Change in normal menstrual cycle. The side effect reported most frequently by women who use Depo-Provera CI for birth controls is a change in their normal menstrual cycle. During the first year of using Depo-Provera CI, you might have one or more of the following changes:
- irregular or unpredictable bleeding or spotting
- an increase or decrease in menstrual bleeding
- no bleeding at all. In clinical studies of Depo-Provera CI, 55% of women reported no menstrual bleeding (amenorrhea) after one year of use and 68% of women reported no menstrual bleeding after two years of use.
- Missed period. During the time you are using Depo-Provera CI for birth controls, you may skip a period, or your periods may stop completely. If you have been receiving your shot of Depo-Provera CI regularly every 3 months, then you are probably not pregnant. However, if you think that you may be pregnant, see your healthcare provider.
Unusually heavy or continuous bleeding is not a usual effect of Depo-Provera CI and if this happens you should see your healthcare provider right away.
With continued use of Depo-Provera CI, bleeding usually decreases and many women stop having periods completely. When you stop using Depo-Provera CI your menstrual period will usually, in time, return to its normal cycle.
